McNemar tests were applied to determine statistical significance of performance changes between consecutive cases [1]}. Asterisked(*) rows have statistically significant improvements at 5% level.Tested values were correct responses (TP or TN) vs. incorrect responses (FP or FN), significance of change in total error rate. Statistically significant improvements were found in moving from LCS to LCS+ (for Ask and Framing), in moving from LCS+ to LCS+Verbal (for Ask), and in moving from LCS+Verbal+CATVAR to Basic Link Processing (for TopAsk).
